GENEVA -- Mercedes-Benz released a major update to its S-Class sedan last year, a high-tech car with a powerful engine and excellent creature comforts. At the 2014 Geneva auto show, Mercedes-Benz unveiled a coupe version.

Along with all-wheel drive, the S550 Coupe gets a unique technology that pushes the side of the car in the outside of a turn up, so that passengers are not pushed to the sides of their seats by inertial forces.
